Word Count and Readability: What the Numbers Mean

Whether you're staying under a tweet limit, hitting an essay requirement, or trying to keep an article skimmable, counting text is a constant task — and readability is the quieter metric that decides whether people actually finish reading. This guide covers what the numbers mean and how to use them.

How counts are measured

Characters

Character count comes in two flavors: with spaces and without. Social platforms and SMS count with spaces (and, as covered in our encoding guide, an emoji or accented letter may count as more than one unit depending on the platform).

Words

A word is normally counted as a run of characters separated by whitespace. That's simple but has edge cases — hyphenated terms, numbers, and contractions can be counted differently by different tools, so two word counters may disagree by a few on the same text.

Reading time

Reading-time estimates are just word count divided by an assumed reading speed — commonly 200–250 words per minute for adults reading on screen. It's an estimate, not a measurement, but it's a useful signal of how much you're asking of a reader.

What readability means

Readability is how easily someone can get through your text. It's driven mostly by two things: sentence length and word length. Long sentences packed with long words force the reader to hold more in their head at once. Popular formulas like the Flesch Reading Ease score combine those factors into a single number, but you don't need a formula to apply the core lesson.

Practical tips for readable writing

• Prefer shorter sentences; break up any that run past ~25 words.
• Choose the simpler word when it means the same thing.
• Use paragraphs and lists to create white space and let the eye rest.
• Read it aloud — anywhere you stumble, the reader will too.
